However, the mechanisms underlying TBT-induced central nervous system (CNS) toxicity remain to be determined especially in freshwater aquatic vertebrates. However, little is known about its reproductive toxicity, In an inhalation study with tributyltin oxide rats were exposed in nose only chambers for 4 hours 5 days a week for 21 -24 treatments for 29 -32 days. Tributyltin oxide - Identification, toxicity, use, water pollution potential, ecological toxicity and regulatory information Note : See Working with the Information on this Page section below for important notes about this data. Comparative toxicity of tributyltin-oxide (TBTO) for fish and snail. Acute Toxicity of Tributyltin Oxide … (bis)tributyltin oxide, tributyltin benzoate, and tributyltin maleate (collectively known as “tributyltin” or “TBT”). Tributyltin oxide (TBTO) is an organotin compound chiefly used as a biocide (fungicide and molluscicide), especially a wood preservative. The enclosed Reregistration There are several case reports claiming irritation of the respiratory Toxicity of Organotins in humans. The most sensitive species was the cyprinid Alburnus alburnus with a 96 hr LC50 of 6-8 ugl TBTF. PubMed:Toxicity of tributyltin and triphenyltin to early life-stages of Paracentrotus lividus (Echinodermata: Echinoidea). Tributyltin (TBT), an organotin compound, is hazardous in aquatic ecosystems. Acute toxicity of bis (tributyltin) oxide in the sweat glands in the rat footpad was investigated by electron microscopy and an energy-dispersive X-ray microanalyzer. TBTO exposure caused serious histological damage to the testis, including reduction in counts of spermatids and spermatozoa and malformation of somatic cells around the seminal duct. Neat tributyltin oxide (TBTO) was purchased from Sigma-Aldrich and used to prepare a 7th World Meeting ORTEP Ass., J.A. After 6-8 h, swelling of mitochondria appeared in the secretory cells of the sweat glands. Tributyltin Compounds. Articles of Tributyltin oxide are included as well. Tributyltin oxide (TBTO) is an organotin compound chiefly used as a biocide (fungicide and molluscicide), especially a wood preservative.Its chemical formula is [(C 4 H 9) 3 Sn] 2 O. Its chemical formula is [ ( The acute inhalation toxicity of Bio-Met-5, bis-tri-n-butyltin-oxide (56359) (Bio-Met-TBTO), tributyltin-fluoride (1983104) (TBTF) and tributyltin-benzoate (4342363) (TBTB) was investigated in Charles-River-rats. Male Wistar rats received an intramuscular injection of 0.5 ml/kg of TBTO. toxicity in both water and sediment samples (ARAÚJO-CASTRO et al., 2009). February 2008 Annals of Applied Biology 60(2):181 - 190 The Physico-chemical and Physiological Bases of Tributyltin Uptake by Mussels, Mytilus. The aim of this study was to assess the acute toxicity of TBT in seawater for the marine copepod T. biminiensis. Chemsrc provides Tributyltin oxide(CAS#:56-35-9) MSDS, density, melting point, boiling point, structure, formula, molecular weight etc. In a study of the chronic toxicity of TBT, Brooke et al. It is a colorless viscous liquid. LC50s range from 6 to 240 ugl TBT. These workers also showed that dibutyltin, the major metabolite of tributyltin, is less effective in inducing apoptosis in vitro, suggesting that the in vivo toxicity is directly attributable to tributyltin. For sperm cells, the toxicity of the two tributyl compounds was significantly greater than that of two triphenyl compounds; for embryos, the triphenyl compounds appeared to be more toxic. The study was initiated with embryos less than 24 h postfertilization and monitored through hatch, maturation, growth, and reproduction under continuous exposure to mean measured TBT concentrations of 5.4, 3.2, 1.3, 0.66, and 0.41 μg TBT/L. The results showed that TBTO is extremely toxic to O. niloticus with 96 h LC 50 of 16.3 μg L-1 using static renewal bioassay test. The stingray, Urolophus jamaicensis, may represent the ideal study organism for the adverse effects of TBTO to elasmobranches. The toxicity of tributyltin oxide to the wood‐boring beetles Lyctus brunneus Steph. These documents include the safe levels of TBT that should protect the majority of species. Unless otherwise specified, all toxicity and environmental chemistry data presented are for tributyltin oxide, a representative compound. The major TBT pesticide is tributyltin oxide. TBTO was shown to be hazardous to nontarget organisms. PubMed:[Soil sorption of bis-(tributylin) oxide]. Temmink, J. H. M., & Everts, J. W. (1988). The effects of tributyltin (TBT) to the life cycle of the estuarine fish Cyprinodon variegatus were examined in a 180-day flow-through exposure. In Proc. Human data summarized by Boyer (1989) suggest that tributyltin oxide is a potent non-allergenic dermal irritant. The activities of serum enzymes and the concentration of serum bilirubin were also analyzed. 1 p. M & T Chemical Co. Jan. 1976. No information was located regarding toxicity of tributyltin oxide in humans following oral exposure.

Previous studies have indicated that TBTO can cause immunotoxicity as an environ-mental pollutant. Cancer bioassays following oral exposure have been conducted in rats and mice. There are no data in humans concerning development of cancer following exposure to tributyltin oxide (TBTO). No developmental effects of nTiO2 were observed at 2 mg/L but concentrations ≥10 mg/L caused hatching inhibition and malformations. The acute toxicity of tributyltin compounds has been studied on several species of freshwater fish. The effect of nTiO2 aggregates on the toxicity of the highly toxic marine antifouling compound tributyltin (TBT) to abalone embryos was also investigated. Based on its review, EPA is now releasing its Reregistration Eligibility Decision (RED) and risk management decision for tributyltin. At the initiation of the 3pecial Review there were 364 TBT anti— fouling paint formulations and 20 formulating intermediates with a total of 61 manufacturers. It is poorly soluble in water (20 ppm) but highly … The present study was carried out to investigate the acute toxicity of TBTO and the effects of its sublethal concentration on brain AChE and gill ATPases activity of tilapia fish, Oreochromis niloticus during acute (3-96 h) and subchronic (7-28 d) exposure periods. Pesticide properties for Tributyltin oxide, including approvals, environmental fate, eco-toxicity and human health issues ------- —2— Registrations: nt.ifoulant paints containing tributyltin (TBT) compounds were initially registered in the early 1960’s. We investigated the toxicity of tributyltin oxide (TBTO) on spermatogenesis in a marine fish, mummichog, Fundulus heteroclitus. CCME (1991 Appendix X) summarised the toxicity data for tributyltin for freshwater animals. Documents pertaining to 2004 Final Acute and Chronic Ambient Aquatic Life Water Quality Criteria for Tributyltin (TBT) for freshwater and saltwater. Toxicity of organotins in humans is most frequently reported as loss of memory and insomnia as well as other symptoms including death ( 4). Summary of unpublished paper presented at the Fifty Annual.SETAC Meeting; Nov. 4-7, 1984, Arlington, Virginia. Tributyltin oxide (TBTO) is the main constituent of tin-based antifouling marine paint used on the hulls of ships to prevent the growth of fouling organisms. Male Wistar rats received an intramuscular injection of 0.5 ml/kg bis (tributyltin) oxide. ENVIRONMENTAL TOXICITY DATA FOR CHEMICALS LISTED UNDER EPCRA SECTION 313 CAS NO.
